都江堰河水猛涨困住8人 直升机往返3次悬停救人

惊险

接近救援点 地面人员却靠近尾桨

下午2点30分左右,正在都江堰景区执行旅游观光任务的驼峰通航当班机长李江华和副机长赖昱,看到了金马河湍急的河流中站着七八名四下张望、不知所措的游客,其中还有几名儿童。

“大概是从鱼嘴出发,往下游大概两三公里的位置。”李江华立即向驼峰通航青城山机场运控中心反馈消息,不到两分钟,上级指示立马中断旅游观光,并用当前的直升机进行救援。

接到任务后,李江华和赖昱立马掉头返回停机坪放下舱内游客,并接上“体重较轻”的刘茗中协助救援。

在这来回直线距离共10公里的飞行中,指挥中心第一时间用互联网调取了事发地的水文,地形以及天气数据情况,传输至舱内。“风速,风向以及湿度对直升机性能是有影响的,我们需要依照相关的数据去保障直升机任务的执行。”李江华说,对于这种河面低空救援,最大的考验是跨河电线,一旦碰触后果严重。

北风7-8m/s,区域温度30℃左右。拿到数据后的李江华和赖昱立马研判,最终选择了向北着陆接近救援点。“不能顺风,必须逆风。”李江华表示,飞机的油量、重量与平衡的计算以及尾桨所在的位置都是要考虑的要素。

“接近救援点时,我们发现了下面当地的一位参与救援的人员,他正往飞机尾桨所在位置靠近,如果被尾桨打到又会发生事故。”舱内人员立马向该救援者打手势示意,让其改向离开,避免了危险发生。

惊心

游客着急往上爬

差点导致飞机失衡

由于在离河岸20多米的事发处,飞机无法完成着陆,只有在离河面20到30厘米处进行悬停。

此刻,摆在李江华和赖昱面前最大的考验则是对空间定向障碍的克服。“这是在宽阔水面进行悬停面临的最大问题,如果没有经过相关悬停的训练,对飞机的平衡把握不好,就会造成操作失控,导致飞机落水。”

李江华目测着远处河岸平面的参考点,了解飞机于所处河面的平衡状态,副驾驶赖昱则参考舱内的仪表,从数据上来把控飞机的悬停姿态。而身后的刘茗中则打开救援之门,蹲在起落架上,指挥协助游客登上直升机。
